Diseases due to infections

Infection is caused by living microbes can involve any organ or system of body.
Infections diseases are the commonest afflictions of human and are major source of morbidity in both developed and developing countries.
The most important aspects of infection include: easy identifiability, sensitivity to antibiotics, communicability, transmission to other people leading to an epidemic and many infections are preventable either by hygienic measeres or by vaccines or by judicious use of drugs.

Types of infection 

  1. Bacterial infection
  2. Protozoal infection
  3. Viral infection
  4. Spirochaetal infection
  5. Rickettsial infection
  6. Nematode (helminthic) infection
  7. Cestode infection
  8. Trematode ( fluke ) infection
  9.  Systemic fungal infecton

1- Bacterial Infectio

  • Infection by gram-positive cocci e.g. staphylococcal, streptococcal
  • Infrction by gram-negative cocci e.g. meningococcal, gonococcal
  • Infection by Gram-positive bacilli e.g. corynrbacterium, listerial, clostridial, B.anthrax
  • Infection by Gram-negative bacilli e.g. haemophilus, legionella, bordetta (whooping cough) cholera, Tularaemia, Melioidosis, Brucella
  • Miscellaneous bacterial infection e.g. Actinomycosis, nocardia, anserobic infection
Mycobactrrial infection e.g. tuberculosis, leprosy and atypical mycobacterial infection

2- Protozoal infection

3- viral infection

  • DNA Viral infection e.g. Herpes virus, parvo virus, pox viruses
  • RNA Viral ingection e.g. Poliomyeliyis, coxsackie and echo viruses, flaviviruses, HIV and AIDS, Respiratory virus and Rabies
  • Viral exanthems e.g. Mumps, measles and rubrlla

4- Spirochaetal Infection

  • Treponemal infection e.g. Syphilis and yaws
  • Leptospirosid

5- Rickettsial Infection

  • Tick and mite-borne spotted fever
  • Flea and louse-borne typhus fever
  • Q.fever

6- Nematode [ Helminthic ] Infection

  • Filariasis
          -Loiasis

  • Cutaneous larva migrans
  • Trichinosis
Intestinal nematodes

  • Strongyloidiasis
  • Ancylostomiasis
  • Ascariasis
  • Tricuriasis
  • Entrrobiasis

7- Cestode Infection


  • Taeniasis ( T.Solium and T.Saginata ) and Cysticercosis
  • Hydated disease 
  • Diphyllobothrium latum and H.nana infection

                  Life cycle of Taenia solium


8- Trematode [ Fluke ] Infection

Acute Viral Hepatitis

Image
  Acute Viral Hepatitis  (Hepatitis A and Hepatitis E) Acute Viral Hepatitis is a systemic infection afecting the liver. Almost all cases of acute viral Hepatitis are caused by one of five viral agents: Hepatitis A (HAV), Hepatitis B (HBV), Hepatitis C (HCV), the HBV-associated delta agent or Hepatitis D Virus (HDV) and Hepatitis E (HEV). All these human hepatitis viruses are RNA viruses, except for hepatitis B, which is a DNA virus but replicates like a retrovirus. While hepatitis A and E are often the cause for sporadic or outbreaks of hepatitis, hepatitis B and C can either clear spontaneously or can lead to chronic infection Mode of Transmission  Hepatitis A: HAV is a non-enveloped RNA virus belonging to the picornavirus family, with four genotypes belonging to one serotype. This agent is transmitted almost exclusively by the fecal-oral route. It is an outbreak prone disease with an incubation period of around four weeks. Person-to-person transmission of ...

Anthrax

-
              Anthrax Anthrax is a serious infectious disease caused by  gram-positive, rod-shaped bacteria known as Bacillus anthracis. Anthrax spores are found naturally in soil and infect both wild and domestic animals such as cattle, sheep, goats, antelope, and deer. Mode of Transmission •Spread of disease in animals: Animals can get infected when they breathe in or ingest spores in contaminated soil, plants or water. • Spread of disease in humans: Person to person transmission is very rare. People normally get infected by anthrax bacillus by: * Inhaling spores * Eating food or drinking water that is contaminated with spores * Getting spores in the body through a cut or scrape in the skin Types of Anthrax • Cutaneous: Entry of anthrax spores into the skin through a cut or scrape, can lead to cutaneous anthrax. The incubation period for cutaneous anthrax is oneseven days. Skin infection begins as a painless, pruritic papule that resembles an...

Cholera

-
             Cholera Cholera is an acute diarrhoeal infection caused by ingestion of food or water contaminated with the bacterium Vibrio cholerae. There are many serogroups of V. cholerae, but only two – O1 and O139 – cause outbreaks. Mode of Transmission • Through faecally contaminated water, food or drinks  • Direct person to-person contact, especially in overcrowded, low sanitation settings, also add to transmission of infection. Signs and Symptoms • Incubation period is from few hours to five days; commonly one-two days  • Typical cases are characterized by sudden onset of profuse, efortless, watery diarrhea followed by vomiting, increased thirst, rapid dehydration, muscular cramps and suppression of urine  • In non-outbreak situations, Cholera may present as simple gastroenteritis or as watery diarrhea  • In an endemic situation, there could be many mild or asymptomatic cases or carriers Complications • Dehydration...
